Abstract

Patente de Invenção: <B>"USINA E PROCESSO PARA A PRODUçãO DE FUNDIDOS DE METAL"<D>. A fim de ser capaz de produzir metal fundido de todos os tipos de condutores de metal usados na metalurgia, e em particular a partir de uma ampla faixa de materiais de carregamento, isto é, combinações quantitativas, uma usina para a produção de metal fundido compreende os seguintes componentes; . um forno a arco elétrico (1) que possui uma abertura de carregamento (11, 21) para um metal fundido e/ou escória e/ou metal diretamente reduzido, em particular ferro, e/ou minério diretamente reduzido e pelo menos um eletrodo (16), e um dispositivo para vazamento de escória (22), e . um vaso conversor de lanceamento de oxigênio (3) guarnecido com pelo menos um dispositivo para vazamento de escória (41). O vaso conversor de laceamento de oxigênio (3) forma uma unidade com o vaso de forno a arco elétrico (1), a qual está conectada via um dique de transbordamento (34), e rigidamente montada na base. A superfície de banho relacionada especificamente ao volume de banho é menor no vaso conversor de lanceamento de oxigênio (3) do que o forno a arco elétrico (1). Finalmente o vaso conversor de lanceamento de oxigênio (3) compartilha uma câmara de reação em comum com o forno a arco elétrico (1), que está disposta acima do nível de banho desses dois vasos.Invention Patent: <B> "PLANT AND PROCESS FOR THE PRODUCTION OF METAL CASTINGS" <D>. In order to be able to produce molten metal from all types of metal conductors used in metallurgy, and in particular from a wide range of loading materials, ie quantitative combinations, a plant for the production of molten metal comprises the following components; . an electric arc furnace (1) which has a loading opening (11, 21) for molten metal and / or slag and / or directly reduced metal, in particular iron, and / or directly reduced ore and at least one electrode ( 16), and a slag leakage device (22), e.g. an oxygen spear converter vessel (3) equipped with at least one device for slag leakage (41). The oxygen lacquering converter vessel (3) forms a unit with the arc furnace vessel (1), which is connected via an overflow dike (34), and rigidly mounted on the base. The bath surface specifically related to the bath volume is smaller in the oxygen spear converter vessel (3) than the electric arc furnace (1). Finally, the oxygen spear converter vessel (3) shares a reaction chamber in common with the electric arc furnace (1), which is arranged above the bath level of these two vessels.
